Tim B, I don't worry too much about the blood, the way i do it is after the coyote is skinned, i dunk the pelt in a bucket of cold water with some dawn dishwashing detergent in it, wring it out, dunk the pelt in a bucket of clean cold water wring out, dunk again and wring out, now take a capfull of downey fabric softner add it to a bucket of cold water put your pelt in and kind of work it a bit, wring the pelt out and let drip dry and you will have the cleanest prettiest coyote pelt you have ever seen, its 5 or 10 minutes of xtra work, but it will pay you in the long run. fwiw Corey
